Abstract
Abstract A connector for a printed circuit board, having a terminal guide for guiding lead terminals, improved to suppress cracking or separation caused by a temperature change in the regions where the lead terminals are soldered to the printed circuit board. The connector has a housing having side walls on both longitudinal ends thereof, the side walls being provided with engaging grooves. The housing mounts a plurality of lead terminals which are led therefrom. The connector also has a terminal guide which is a substantially tabular member made from an insulating material provided on both longitudinal ends thereof with projections for engagement with the engaging grooves of the housing. The terminal guide has a plurality of lead terminal insertion holes formed at the same pitch as the lead terminals so as to receive these lead terminals. At least one stress relieving portion in the form of a slit or an elongated slot or aperture is formed in the terminal guide so as to localize any thermal expansion or contraction of the terminal guide occurring in the longitudinal direction thereof.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
106 words
A connector for a printed circuit board, comprising: a housing; an elongated terminal guide mounted in said housing and having a plurality of lead terminal insertion holes spaced longitudinally apart for receiving lead terminals, and a plurality of stress relieving openings disposed between said longitudinally adjacent lead terminal insertion holes for absorbing thermal expansion or contraction of said terminal guide in a longitudinal direction; and a plurality of lead terminals mounted in respective ones of said lead terminal insertion holes; wherein said stress relieving openings comprise slits formed in said terminal guide, said slits each having an opening in a longitudinal edge of said terminal guide.
Claim 2
Dependent Claim
106 words
A connector for a printed circuit board, comprising: a housing; an elongated terminal guide mounted in said housing and having a plurality of lead terminal insertion holes spaced longitudinally apart for receiving lead terminals, and a plurality of stress relieving openings disposed between said longitudinally adjacent lead terminal insertion holes for absorbing thermal expansion or contraction of said terminal guide in a longitudinal direction; and a plurality of lead terminals mounted in respective ones of said lead terminal insertion holes; wherein said stress relieving openings comprise slits formed in said terminal guide, said slits each having an opening in a longitudinal edge of said terminal guide.
Claim 3
Dependent Claim
158 words
A connector for a primed circuit board, comprising: a housing having two opposing side walls that are provided with engaging grooves; an elongated terminal guide mounted in said housing and having a plurality of lead terminal insertion holes spaced longitudinally apart for receiving lead terminals, and a plurality of projections that engage the engaging grooves of said housing; and a plurality of lead terminals mounted in respective ones of said lead terminal insertion holes, said lead terminals being orthogonally bent; wherein said terminal guide is made of an insulating synthetic resin and is provided with at least one stress relieving opening disposed between two longitudinally adjacent ones of said lead terminal insertion holes for absorbing thermal expansion or contraction of said terminal guide in a longitudinal direction; wherein said at least one stress relieving opening one stress relieving slit, said at least one stress relieving slit each having an opening in a longitudinal edge of said terminal guide.
Claim 4
Dependent Claim
158 words
A connector for a primed circuit board, comprising: a housing having two opposing side walls that are provided with engaging grooves; an elongated terminal guide mounted in said housing and having a plurality of lead terminal insertion holes spaced longitudinally apart for receiving lead terminals, and a plurality of projections that engage the engaging grooves of said housing; and a plurality of lead terminals mounted in respective ones of said lead terminal insertion holes, said lead terminals being orthogonally bent; wherein said terminal guide is made of an insulating synthetic resin and is provided with at least one stress relieving opening disposed between two longitudinally adjacent ones of said lead terminal insertion holes for absorbing thermal expansion or contraction of said terminal guide in a longitudinal direction; wherein said at least one stress relieving opening one stress relieving slit, said at least one stress relieving slit each having an opening in a longitudinal edge of said terminal guide.
